During the early months of the COVID-19 pandemic, Jay Van Bavel, a psychologist at New York University, wanted to identify the social factors that best predict a person’s support for public-health measures, such as physical distancing or closing restaurants.

The Risk of Vaccinated COVID Transmission Is Not Low
My two-year-old tested positive for COVID last month. My mind-numbing and costly project to keep him uninfected prior to his vaccinations had proven an abject failure. I was angry—and surprised. During the time he was likely infected, he had only been around vaccinated people when indoors. Although we know the absolute risk of serious illness […]

This idea of “emissions inequality” underscores how nations that are contributing to climate change the most are disproportionately affecting regions that produce far less greenhouse gases. But the report by the World Inequality Lab also shows that the […]
The Ups and Downs of a Great Vertical Migration
Every evening, after twilight gives way to dark, hordes of marine creatures—from tiny zooplankton to hulking sharks—rise from the deep to spend the night near the surface. They revel in the upper waters, feeding and mating, before retreating back down before dawn. Known as the diel vertical migration, this mass movement is often heralded as […]
As Arctic Sea Ice Melts, Killer Whales Are Moving In
One of the ocean’s most fearsome predators is muscling into new parts of the icy Arctic Ocean. Orcas, also known as killer whales, are showing up in places they’ve never been spotted before. Scientists believe melting sea ice is to blame. “[Killer whales] will normally avoid ice to avoid entrapment and suffocating,” said Brynn Kimber, […]
